Odysseus is the next one on the list of legendary great sailors. He was the king of Ithaca and 3200 years ago he fought on the Trojan War but his greatest adventure started after it, when he was trying to return home to Ithaca that is on the Ionian Greece coast, a long voyage from Troy, even today, around the Peloponnese.

the conditions that made the byzantine empire vulnerable to attacks by the muslin turks were the sack of constantinople by western crusaders, the conquests of the sultanate of rum, presence of rival kingdoms and finally the set up of fiefdoms at the empire which were owned by the ghazis (turkish warriors).
